Pt1 upper spd falling
Upper speed threshold value up to which Pt1 filter time constant Pt1 time const 1 drop
[3694.1] acts when the speed setpoint changes from a higher to a lower level. If the
speed drops below this threshold value, filter time constant Pt1 time const 2 drop
[3695.1] starts acting.
Line no.
Operating line
[3699.1]
Pt1 lower spd falling
Lower speed threshold value up to which Pt1 filter time constant Pt1 time const 2 drop
[3695.1] acts when the speed setpoint changes from a higher to a lower level. If the
speed drops below this threshold value, filter time constant Pt1 time const 2 incr
[3697.1] starts acting.
Line no.
Operating line
[3997.1]
Fan PWM-Min
Minimum PWM controller load value of fan control (minimum control range value).
Line no.
Operating line
[3998.1]
Fan PWM-Max
Maximum PWM controller load value of fan control (maximum control range value).
Line no.
Operating line
[4269.1]
Ion curr lim, low
Ionization current limit from which the minimum speed is set to the current speed.
Line no.
Operating line
[4270.1]
Ion curr lim, change
Hysteresis added to the Ion curr lim, low [4269.1].
From Ion curr lim, low [4269.1] + Ion curr lim, change [4270.1], the lower speed limit is
reduced every 0.2 seconds.
Line no.
Operating line
[4398.1]
IonCurrLimPosSpdSlope
Value shows the increase in speed per second, when ionization current limitation
comes into effect and when an excessively low ionization current is present.
Line no.
Operating line
[4397.1]
IonCurrLimNegSpdSlope
Value shows the decrease in speed per second, after ionization current limitation
comes into effect and when the ionization current has risen again.
Line no.
Operating line
[4273.1]
Ion curr lim, filter
Filter time constant for ionization current maintenance limit.
